Comparing COVID-19 Vaccines

Comparing COVID-19 Vaccines is the first step you should be doing before getting your vaccines. Getting a handle on the COVID-19 vaccine market and sales is definitely a moving target, with governments subsidizing manufacturing and distribution, and prices varying from country to country. Morningstar noted on May 3, 2021, that the Pfizer-BioNTech and Moderna COVID-19 vaccines account for more than 60% of the total COVID-19 market estimate in 2021 and 2022. The overall COVID-19 market. The overall market for COVID-19 drugs and vaccines is projected to peak this year at $67 billion, drop to $61 billion in 2022. Most likely, as more and more of the world’s population become vaccinated, Morningstar projects the overall COVID-19 market to be $8 billion annually beginning in 2023, but could drop as low as $500 million.

The 8 best-selling COVID-19 vaccines and drugs in the first quarter of 2021 are:

#1. Pfizer-BioNTech COVID-19 vaccine. U.S. sales were $2.038 billion; global sales were $5.833 billion.

#2. Moderna COVID-19 vaccine. U.S. sales, $1.358 billion; global sales, $1.733 billion.

#3. Gilead Sciences’ remdesivir (Veklury). An antiviral drug, U.S. sales for the quarter were $820 million; global sales, $1.456 billion.

#4. Eli Lilly’s bamlanivimab and etesevimab. The antibody cocktail brought in $650.6 million in U.S. sales in the first quarter.

#5. Regeneron Pharmaceuticals’ casirivimab and imdevimab (REGEN-COV). Regeneron’s antibody cocktail reported $262 million in Q1 U.S. sales and $438.8 million globally.

#6. AstraZeneca-Oxford COVID-19 vaccine. No U.S. sales (not yet submitted for authorization); global sales of $275 million for the first quarter.

#7. Sinovac Biotech’s CoronaVac (vaccine). No U.S. sales. First-quarter global sales were $264.5 million.

#8. Johnson & Johnson’s single-shot COVID-19 vaccine. For the first quarter, $100 million in U.S. sales.

Comparing COVID-19 Vaccines By Vaccine Details;

Scientific teams around the world have developed successful Covid-19 vaccines in incredibly short order. In a feat that even a couple of years ago would have seemed completely out of reach, vaccines to protect against the new disease were being used before the first anniversary of the disclosure that a new threat existed. This is truly extraordinary. Comparing COVID-19 Vaccines is not to judge vaccine or the say which vaccine is better then other! We just summary available information for easy understanding.

Comparing COVID-19 Vaccines: Pfizer-BioNTech

The Pfizer-BioNTech COVID-19 vaccine was sent to the FDA for possible Emergency Use Authorization (EUA) on Friday, November 20 and authorized on December 11. It is an mRNA vaccine that codes for the virus’s spike protein and is encapsulated in a lipid nanoparticle. Once injected, the cells churn out the spike protein, triggering the body’s immune system to recognize the virus. In Phase III trials, it demonstrated 95% efficacy. The Pfizer-BioNTech vaccine requires storage at about -94 degrees F, which requires specialized freezers.

Now authorized in the U.S. for adolescents 12 to 15 years of age.

Type: mRNA

Doses: 2, 21 Days Apart

EUA Date: December 11, 2020

Price: $19.50 per dose for first 100 million doses

Efficacy: About 95%. Apparently 100% at preventing hospitalization and death.

Variants: Lab data suggest “quite effective” against the UK variant as well as the South African and Latin American variants. Also, data suggests it is effective against hospitalization of the Delta variant but more data is needed.

Comparing COVID-19 Vaccines: Moderna

On November 16, Moderna issued a preliminary data readout out of its COVID-19 vaccine, suggesting an efficacy rate of 94.5%. It was authorized by the FDA on December 19. Like the Pfizer-BioNTech vaccine, it is an mRNA vaccine. Unlike that vaccine, however, the Moderna vaccine is stable at 36 to 46 degrees F, about the temperature of a standard home or medical refrigerator, for up to 30 days and can be stored for up to six months at -4 degrees F.

Moderna reported in May 2021, a Phase II/III trial of 3,732 children ages 12 to 17 in the U.S. demonstrated their vaccine produced an immune response equivalent to earlier findings in adults. Data also suggested the vaccine was 93% effective after one dose at preventing mild COVID-19 cases. It was generally well tolerated, and plans to submit to the FDA in early June for expanded authorization for adolescents.

Type: mRNA

Doses: 2, 28 Days Apart

EUA Date: December 18, 2020

Price: $25-$37 per dose

Efficacy: About 95%. Apparently 100% at preventing hospitalization and death.

Comparing COVID-19 Vaccines: AstraZeneca-University of Oxford

On November 23, AstraZeneca and the University of Oxford announced high-level results from an interim analysis of their COVID-19 vaccine, AZD1222. The analysis was from the trials in the UK and Brazil and demonstrated efficacy of up to 90%. The vaccine was effective at preventing COVID-19, with no hospitalizations or severe cases in people receiving it. There were a total of 131 COVID-19 positive cases in the interim analysis group. One dosing regimen was given at a half dose and demonstrated 90% efficacy, followed by a full dose at least one month apart. Another dosing regimen demonstrated 62% efficacy when given two full doses at least one month apart. The combined analysis showed average efficacy of 70%. The AstraZeneca vaccine can be stored, transported and handled at normal refrigerated conditions, about 36-46 degrees F for at least six months and administered within existing healthcare settings.

On March 25, 2021, AstraZeneca released primary analysis that the vaccine demonstrated 76% efficacy against symptomatic COVID-19, 100% efficacy against severe or critical disease and hospitalizations, and 85% efficacy against symptomatic COVID-19 in people 65 years and older.

The AstraZeneca and University of Oxford’s vaccine uses technology from an Oxford spinout company, Vaccitech. It deploys a replication-deficient chimpanzee viral vector based on a weakened version of a common cold virus (adenovirus) that causes infections in chimpanzees. It contains the genetic materials of the spike protein. After vaccination, the cells produce the spike protein, stimulating the immune system to attack the SARS-CoV-2 virus.

The COVID-19 vaccine developed by AstraZeneca and the University of Oxford has been linked to blood clots. More than a dozen European countries have halted the distribution of the AstraZeneca-Oxford vaccine as a result. To date, there have been about 222 suspected blood clotting cases in Europe with more than 30 deaths linked to the AstraZeneca-Oxford vaccine, out of 34 million vaccinations. In these cases, the clots are pulmonary embolism, deep vein thrombosis (DVT) or thrombocytopenia.

In May, due to concerns over blood clots, in England it was recommended that people under the age of 40 should receive a different vaccine. There have been cases of reported venous strokes, but until May 25, there were no reported cases of arterial thrombosis (clots in the arteries). There was a report of an arterial stroke in the UK published online in Journal of Neurology Neurosurgery & Psychiatry in late May.

Type: Adenovirus-based

Doses: 2, 28 Days Apart

Likely EUA Date: Authorized in Europe on January 12, 2021, and other countries, but unlikely in the U.S. until spring

Price: $2.15 (U.S.) in the EU; $3-4 (U.S.) in the UK and U.S.; $5.25 (U.S.) in South Africa

Efficacy: Currently about 70% overall.

Variants: At least one study finds it has little effect against the South African variant, but appears effective against UK and Brazilian variants.

Comparing COVID-19 Vaccines: Johnson & Johnson

Johnson & Johnson announced on November 15 that it initiated a second global Phase III trial of its Janssen COVID-19 vaccine. They expect to enroll up to 60,000 volunteers worldwide.

Whereas all of the other three vaccine candidates require two doses about 28 days apart, the J&J vaccine only requires a single dose. Interim results from its Phase I/IIa trial demonstrated a single dose of the vaccine induced a robust immune response and was generally well-tolerated. The ENSEMBLE 2 study evaluated a two-dose regimen as well.

The Phase III ENSEMBLE trial demonstrated the single-shot vaccine is 66% effective overall in preventing moderate-to-severe COVID-19, 28 days after vaccination. However, it demonstrated 100% efficacy ad preventing severe disease after day 49.

The vaccine uses the company’s AdVac technology platform, which it used to develop its approved Ebola vaccine and its Zika, RSV and HIV investigational vaccine candidates. It revolves around the use of an inactivated common cold virus, similar to what the AstraZeneca-University of Oxford program utilizes.

In April 2021, the CDC and FDA recommended a pause on distribution of the Johnson & Johnson COVID-19 vaccine. Six cases of a “rare and severe” type of blood clot had been identified. The clots observed with the J&J vaccine are cerebral venous sinus thrombosis (CVST) in combination with low levels of blood platelets, called thrombocytopenia. All six of the cases were in women between the ages of 18 and 48 and occurred six to 13 days after receiving the single-dose vaccine. These six cases were extremely rare, out of more than seven million doses administered. An FDA advisory committee is expected to make a recommendation on resuming distribution on April 23.

Type: Adenovirus-based

Doses: 1

Authorized

Price: $10 per dose

Efficacy: In J&J’s global clinical trial, it demonstrated 66% efficacy at preventing symptomatic COVID-19 infections. In the U.S. it was slightly higher, 72%. Appears to be 100% effective at preventing hospitalizations and death.

Variants: Based on clinical studies in Africa, UK and Latin America, there is evidence the vaccine is effective against the variants, although less so against the South African and Latin American strains.

Comparing COVID-19 Vaccines: Russia’s Sputnik V Vaccine

Around November 11, Russia’s National Research Center for Epidemiology and Microbiology, which Russia authorized for use in August—ahead of even beginning a Phase III trial—claimed had an efficacy rate of 92% after the second dose. It was based on a first interim analysis 21 days after the first injection during the ongoing Phase III study. On November 24, the organization claimed 95% efficacy based on new preliminary data. On December 14, 2020, they reported efficacy of 91.4%. It also offered to share one of its two human adenoviral vectors with AstraZeneca to increase the efficacy of the AstraZeneca vaccine.

Russia’s Gamaleya research institute appears to be focused on potentially marketing their vaccine worldwide. Even the name of the vaccine has emphasized the idea of a race. The organization has indicated a dose of the vaccine will cost no more than $10, about half the cost of the Pfizer vaccine. The organization has also predicted they could produce 1 billion doses in the next year. At this time, aside from Russia, it will potentially be sold in India, Korea, Brazil, China, and Hungary. The Hungarian government is the only European Union country to express interest to date.

On February 2, 2021, The Lancet published Phase III data demonstrating a 91.6% efficacy against the original strain of the virus.

This vaccine, even into late May 2021, remains controversial. It is being distributed in 39 countries and expected to be distributed in 27 more. However, inconsistent clinical trial data has scientists question the analyses, and wondering if it has been manipulated. It was originally authorized in Russia in August 2020 after being tested on only 38 people. The Gamaleya Research Institute published results showing 95% efficacy in The Lancet but did not include raw data. In mid-May, a group of international scientists highlighted concerns over patterns in The Lancet data consistent with data manipulation.

Type: Adenovirus-based

Doses: 2

Likely EUA Date: Not applicable in the U.S.

Price: $10 per dose

Efficacy: 91.4%

Variants: Unknown. Clinical trial data was largely conducted in Russia prior to the emergence of major variants.

Comparing COVID-19 Vaccines: Sinovac Biotech

On January 13, 2021, China-based Sinovac Biotech reported that its COVID-19 vaccine had a 50.38% efficacy in late-stage clinical trials in Brazil. The company’s clinical trials are demonstrating dramatically varying efficacy rates. In Indonesia, a local trial demonstrated an efficacy rate of 65%, but the trial had only 1,620 participants. Turkey reported an efficacy rate of 91.25% in December 2020. Another trial in Brazil run by a local partner, Butantan Institute, reported last week a 78% efficacy rate in mild cases while 100% against severe and moderate infections. It is an inactivated vaccine that uses inactivated SARS-CoV-2 viruses.

In May 2021, WHO requested more data from the company regarding the safety of the shot and its manufacturing process. They want to determine if it is compliant with WHO standards and expect to make a decision in June.

Type: Inactivated SARS-CoV-2 virus

Doses: 2

Likely EUA Date: Not applicable in the U.S.

Price: $60 per dose in China ($29.75 per dose)

Efficacy: 50.38% to 91.25%, depending on the clinical trial

Variants: Unknown, although a study in Brazil demonstrated 50.4% efficacy at preventing symptomatic infections.

Comparing COVID-19 Vaccines: Novavax

On January 28, 2021, Novavax announced that its COVID-19 vaccine, NVX-CoV2373, hit the primary endpoint with a vaccine efficacy of 89.3% in its Phase III trial in the UK. The vaccine is a protein-based COVID-19 vaccine candidate. It also has data from the South Africa Phase IIb trial and several Phase I, II and III trials. It has demonstrated high clinical efficacy against the UK and South Africa variants as well.

The vaccine contains a full-length, prefusion spike protein made using the company’s recombinant nanoparticle technology and its proprietary saponin-based Matrix-M adjuvant. It is stable at 2 to 8 degrees C and shipped in a ready-to-use liquid formulation.

Type: Protein-based vaccine

Doses: 2

Likely EUA Date: Possibly in March or February 2021 in the UK; possibly Q1 2021 or later in the U.S. Most recent suggestion for EUA in the U.S. was May 2021.

Price: $16 in the US

Efficacy: 90.4%

Variants: Effective against UK and South African

Comparing COVID-19 Vaccines: CanSino Biologics

CanSino Biologics vaccine was co-developed with the Chinese military. It has an efficacy rate of 65.7% at preventing symptomatic cases. This is based on a multi-country analysis first posted on Twitter by Faisal Sultan, Pakistan’s health adviser, on February 8, 2021. The Phase III trial includes 30,000 participants and demonstrated 90.98% efficacy in preventing severe disease. It only requires a single shot. It has agreed to supply 35 million doses to Mexico and is in talks with Malaysia for 3.5 million shots. Pakistan is running one of the largest trials, and has contracted for 20 million shots. It is also working with the WHO for approval for the vaccine through the Covax program. It is also planning a trial with Russia to determine if swapping the second dose of Russia’s Sputnik V vaccine with Can Sino would produce the same or better protection.

CanSino Biologics announced it will initiate clinical trials next week of an experimental COVID-19 vaccine that is inhaled, instead of injected. This follows some controversy over China’s COVID-19 vaccines, which the director of the Chinese Center for Disease Control publicly admitted, “don’t have very high protection rates.” As a result, the Chinese government was considering alternate vaccines to increase vaccine efficacy in the country. In a trial in February, the vaccine demonstrated efficacy of 65.7% in preventing symptomatic cases. But in April, the company noted that its efficacy rate seemed to drop over time but should have a rate of 50% or more five to six months after inoculation.

A study out of Mexico’s National Institute of Medical Sciences and Nutrition, the CanSino vaccine only offers protection for about six months. They also believe that a second dose of the vaccine would likely be necessary.

Type: Viral vector, loading an antigen from the SARS-CoV-2 virus onto an adenovirus.

Doses: 1

Price: Unknown

Likely EUA Date: Not applicable in the U.S.

Efficacy: 65.7% at preventing symptomatic cases; 90.98% efficacy in preventing severe disease.

Variants: Unknown

Comparing COVID-19 Vaccines: Bharat Biotech

On April 22, 2021, India’s Bharat Biotech reported interim data from the Phase III trial of its COVID-19 vaccine COVAXIN, which demonstrated a 100% efficacy against severe infection. The vaccine was developed with seed strains from the Indian Council of Medical Research’s (ICMR) National Institute of Virology. It is a highly purified and inactivated vaccine. A second interim analysis suggested a 78% efficacy against mild, moderate and severe disease, and 70% efficacy against asymptomatic disease. Does not require sub-zero storage, no reconstitution requirement, and ready to use liquid in multi-dose vials, stable at 2-8 degrees C.

The company indicated on May 25, 2021, that it expects its vaccine to receive the WHO’s emergency use listing between July and September. Regulatory approvals were ongoing in more than 60 countries, including the U.S., Brazil and Hungary. It is authorized in 13 countries.

Type: Inactivated SARS-CoV-2 virus using Whole-Virion Inactivated Vero Cell platform technology.

Doses: 2, 28 days apart

Likely EUA Date: Not applicable in the U.S.

Price: ₹150 or about $2 (U.S.), although that appears to be the low-end of the open-market price in India

Efficacy: 100% against severe infection; 78% against mild, moderate and severe; 70% against asymptomatic

Variants: Wildtype; can neutralize UK variant

Comparing COVID-19 Vaccines: Abdala and Soberana 2 Vaccines

The Cuban government announced on June 22, 2021, that its three-shot Abdala vaccine has a 92% efficacy rate against COVID-19. They provided no details on clinical testing.

It had also recently announced that another of its COVID-19 vaccines, Soberana 2, had an efficacy of 62% after two of its three shots.

Abdala is created by Cuba’s Center for Genetic Engineering and Biotechnology. Soberana 2 was developed by a state-run biopharma company, BioCubaFarma, which oversees the Finlay Institute and Center for Genetic Engineering and Biotechnology.

Reportedly Cuba has five coronavirus vaccine candidates.
