Development of mRNA Based Vaccines Has Demonstrated the Effectiveness and Versatility

“According to Market.us, in 2021, the revenue of the mRNA market was USD 50 billion and it is expected that the revenue will decrease to USD 23 billion by 2035.”

The Pfizer- BioNTech vaccine, BNT162b2 Statistics

Pfizer- BioNTech vaccine, BNT162b2 uses mRNA to create the receptor binding domain of the spike protein of SARS-CoV-2. According to mRNA statistics Clinical trials involving tens of thousands of participants have shown that the Pfizer-BioNTech vaccine is highly effective in preventing symptomatic COVID-19. It has demonstrated efficacy rates of around 95% in preventing COVID-19 infection in individuals without prior exposure to the virus.

Efficacy

• The efficiency of Pfizer- BioNTech vaccine, BNT162b2 vaccine remains consistently above 70% in both the age group 6 to 23 months and ages 6 months to 4 years.
• The vaccine was 95% effective in protecting trial participants from COVID-19 for those 16 years and older.
• The vaccine was 100% effective for those 12 to 15 years old.
• 90.7% effective for those 5 to 11 years old.

Common Side Effects

No serious adverse events were observed in the phase 3 clinical trial for the Pfizer- BioNTech vaccine, BNT162b2. The mild local side effects are observed such as heat, pain, redness, and swelling. The other systemic side effects including fatigue, fever, headache, myalgia, and arthralgia occur more frequently with the vaccine than with placebo, with most occurring within 1 to 2 days following vaccination.

• The most common reaction with the vaccine was pain at the injection site within one week of vaccination.
• The majority of common reactions are seen in individuals aged 26 years and above.
• Less than 1% of participants reported severe pain and it was most common in individuals aged 55 years and above.
• In the trials, the younger individuals aged 16 to 55 years reported systemic events.
• Most of the systemic reactions are seen in the second dose of COVID-19 as compared to the first dose.
• The incidence of systemic reactions was less than 1% in the first vaccine and less than 2% in the second vaccine.
• About 3.8% of individuals reported fatigue.
• 2% of individuals reported headaches.
• Only 0.2% of vaccine receivers and 0.1% of placebo recipients reported fever up to 40 °C in the first dose of vaccine.
• About 0.8% of vaccine recipients and 0.1% of placebo recipients reported fever up to 40 °C in the second dose of vaccine.
• Adverse events were more commonly reported among vaccine recipients (27 %) compared to the placebo group (12 %).

Side effects and adverse reactions to mRNA vaccines against SARS-CoV-2

The Moderna vaccine, mRNA-1273 Vaccine Statistics

Moderna vaccine, mRNA-1273 uses mRNA to create the SARS-CoV-2 spike protein stabilized in its perfusion conformation. Clinical trials involving tens of thousands of participants have shown that the Moderna vaccine is highly effective in preventing symptomatic COVID-19. It has demonstrated efficacy rates of around 94-95% in preventing COVID-19 infection in individuals without prior exposure to the virus.

The COVID-19 vaccine mRNA-1273 later brands named Spikevax, was the company’s first product approved by the Federal Drug Administration. Its massive use is seen in Western countries. Spikevax was among the world’s second bestselling pharmaceutical products in 2022, generating over USD 21 billion in revenues.

Efficacy

• The efficacy of the vaccine against COVID-19 was 36.8% among 2 to 5-year-olds.
• The efficacy of the vaccine among adults aged 6 to 23 months was 50.6% at the time when the omicron variant was the predominant circulating variant.

Common Side Effects

• Similar to the Pfizer-BioNTech vaccine, the Moderna vaccine can have side effects, although the majority of them are mild and temporary.
• Common side effects reported with the Moderna vaccine include pain or swelling at the injection site, fatigue, headache, muscle pain, chills, fever, and nausea. These side effects typically resolve within a few days.

Serious Adverse Events

• Serious adverse events associated with the Moderna vaccine are rare but they can occur. In rare instances, severe allergic reactions and anaphylaxis have been reported. However, the overall occurrence of anaphylaxis after receiving the Moderna vaccine is extremely low.

Leading Products by Sales Worldwide in 2022 Statistics

• During the COVID-19 pandemic, the COVID-19 vaccine Comirnaty was top top-performing pharmaceutical product, generating a revenue of USD 40.8 billion.
• The Spikevax which is the Moderna COVID-19 vaccine was the second largest selling pharmaceutical product which generated revenue of USD 21.8 billion in 2022.
• Humira, Keytruda, and Paxlovid are the other most-selling pharmaceutical products worldwide in 2022.
