The Israel Ministry of Health, Pfizer, and BioNTech released data showing significantly lower COVID-19 incidences in fully vaccinated individuals with the Pfizer-BioNTech vaccine. Findings indicate vaccinated individuals were 44 times less likely to develop symptomatic COVID-19 and 29 times less likely to die. Vaccine effectiveness was measured at 97% against symptomatic cases and severe outcomes, and 94% against asymptomatic infections. This comprehensive evidence supports ongoing global vaccination efforts amidst the pandemic.

The Israel Ministry of Health, Pfizer, and BioNTech announced significant findings from a real-world study showing a 97% effectiveness of the Pfizer-BioNTech COVID-19 Vaccine in preventing symptomatic COVID-19, severe cases, and deaths. This data, derived from health surveillance from January to March 2021, showcases the impact of Israel's vaccination efforts, particularly against the B.1.1.7 variant. Further, the vaccine demonstrated 94% effectiveness against asymptomatic infections, emphasizing its role in controlling the pandemic and supporting ongoing immunization campaigns globally.

Pfizer and BioNTech have initiated a Phase 1/2/3 trial to evaluate a third dose of their COVID-19 vaccine, BNT162b2, aimed at studying safety and immunogenicity against evolving SARS-CoV-2 variants. Participants who received the initial two doses will be offered a booster dose 6 to 12 months later. They are also in discussions with regulatory authorities for a variant-specific mRNA vaccine, potentially targeting the B.1.351 lineage. The companies seek to ensure robust immunity and prepare for possible future vaccine adaptations, with ongoing assessments expected over two years.

Pfizer (NYSE: PFE) and BioNTech (Nasdaq: BNTX) are evaluating a third dose of their COVID-19 vaccine, BNT162b2, to assess safety and immunity against circulating and emerging SARS-CoV-2 variants. This study will involve participants from a previous Phase 1 trial, who will receive the booster 6 to 12 months post-initial vaccination. Additionally, the companies are in talks with the FDA and EMA for a clinical study on a variant-specific vaccine. The goal is to ensure preparedness against future variants while maintaining current vaccine effectiveness.

BioNTech (BNTX) and Pfizer have submitted data to the FDA to update the Emergency Use Authorization for their COVID-19 vaccine. The proposed change would allow the vaccine to be stored at -25°C to -15°C for up to two weeks, providing better logistical flexibility for pharmacies and vaccination centers. This submission includes stability data from the last nine months of development. The current storage requirement necessitates ultra-cold temperatures between -80ºC and -60ºC. If approved, the updated storage guidelines would enhance accessibility for vaccine distribution.

Pfizer and BioNTech have initiated a global Phase 2/3 trial for their COVID-19 vaccine (BNT162b2) involving about 4,000 healthy pregnant women in several countries, including the U.S. and U.K. The trial aims to assess the vaccine's safety and immunogenicity in this vulnerable group. Participants will be unblinded post-delivery, allowing those who received a placebo to be vaccinated. The trial follows prior studies indicating no reproductive toxicity in animals. This initiative marks a step towards ensuring vaccine safety for crucial populations.

On February 17, 2021, Pfizer and BioNTech released findings from an in vitro study confirming the Pfizer-BioNTech COVID-19 vaccine (BNT162b2) neutralizes the South African variant of SARS-CoV-2. Despite reduced neutralization against the variant's mutations, all sera tested effectively neutralized the variant. No evidence suggests that the variant escapes protection from the vaccine in vaccinated individuals. The companies are evaluating other variants and preparing for a potential updated mRNA vaccine. The vaccine is under Emergency Use Authorization in the U.S.

Pfizer and BioNTech have secured a new agreement with the European Commission to deliver an additional 200 million doses of the COMIRNATY vaccine, bringing the total supply to 500 million doses by the end of 2021. The agreement allows for an option of 100 million more doses. With this arrangement, at least 250 million Europeans could be vaccinated. Both companies are ramping up manufacturing capacity to meet global demand, aiming for around two billion doses by the end of 2021.

The U.S. government has exercised its option to purchase an additional 100 million doses of the Pfizer-BioNTech COVID-19 vaccine, bringing the total to 300 million. The government will pay $1.95 billion for these doses, aimed at vaccinating 150 million people. Pfizer and BioNTech are committed to increasing vaccine supply to combat COVID-19. The vaccine has been authorized for emergency use in individuals aged 16 and older. Manufacturing primarily occurs at Pfizer's Kalamazoo facility, utilizing BioNTech's proprietary mRNA technology.
