COVID-19 Vaccines
By the end of November 2021, scientists estimate that mRNA COVID-19 vaccines had prevented at least 1 million deaths, 10 million hospitalizations, and 36 million SARS-CoV-2 infections in the United States. Sometimes people who are fully vaccinated get a breakthrough infection, meaning that they test positive for SARS-CoV-2 or become ill with ...
Long-term effectiveness of COVID-19 vaccines against infections
In this rapid living systematic evidence synthesis and meta-analysis, we searched EMBASE and the US National Institutes of Health's iSearch COVID-19 Portfolio, supplemented by manual searches of COVID-19-specific sources, until Dec 1, 2022, for studies that reported vaccine effectiveness immediately and at least 112 days after a primary vaccine series or at least 84 days after a booster dose.

Effectiveness of COVID-19 vaccines to prevent long COVID: data from
Our recent study using data from more than 20 million participants has shown that COVID-19 vaccines consistently prevent long COVID symptoms in adults, with meta-analytic calibrated subdistribution hazard ratio (sHRs) of 0·54 (95% CI 0·44-0·67) in CPRD GOLD, 0·48 (0·34-0·68) in CPRD AURUM, 0·71 (0·55-0·91) in SIDIAP, and 0·59 (0·40-0·87) in CORIVA.1 In addition, when ...
Cochrane review of COVID-19 vaccines shows they are effective
They suggest that further research compares new vaccines with those already in use. The current review analysed data available up to November 2021. Since then, analyses have been updated and will continue to be made publicly available every two weeks by the COVID-NMA Initiative, which provides live mapping of COVID-19 trials. A living ...
Evaluating COVID-19 vaccines in the real world
The effectiveness of the mRNA vaccines in preventing COVID-19 disease progression in 2021 set new expectations about the role of prevention interventions for the disease. Efficacy observed in the trials was more than 90%.1,2 The efficacy of other vaccines evaluated in large randomised trials, such as the Oxford-AstraZeneca (70%) and Sputnik V (91%) vaccines, have been criticised for elements ...

The Updated COVID Vaccines Are Here: 9 Things to Know
The FDA authorized an updated version of a vaccine Novavax developed to target the XBB.1.5 strain. Individuals 12 and older previously vaccinated with a COVID-19 vaccine (and who have not already been vaccinated with a recently updated mRNA COVID-19 vaccine) are eligible to receive one dose; unvaccinated individuals can receive two doses.
COVID vaccines and safety: what the research says
There is no question that the current vaccines are effective and safe. The risk of severe reaction to a COVID-19 jab, say researchers, is outweighed by the protection it offers against the deadly ...

COVID-19 vaccines. Everyone, everywhere, should have access to COVID-19 vaccines. Major progress has been made with the COVID-19 vaccination response, and it is critical to continue the progress, particularly for those most at risk of disease. WHO recommends a simplified single-dose regime for primary immunization for most COVID-19 vaccines ...
COVID-19 Vaccine Effectiveness
Receiving an updated 2023-2024 COVID-19 vaccine can restore and provide enhanced protection against the variants currently responsible for most infections and hospitalizations in the United States. New data from CDC show that the updated COVID-19 vaccines were effective against COVID-19 during September 2023 - January 2024, including against ...

2023-2024 Pfizer-BioNTech COVID-19 vaccine. This vaccine was first tested against the original strain of the COVID-19 virus. That strain began spreading at the end of 2019. In December 2020, the Pfizer-BioNTech COVID-19 vaccine two-dose series was found to be both safe and 91% to 95% effective in preventing COVID-19 infection in people age 18 ...
New Comprehensive Review Examines Potential Harms of COVID-19
WASHINGTON — A new report from the National Academies of Sciences, Engineering, and Medicine reviews evidence for 19 potential harms of the COVID-19 vaccines, and for nine potential shoulder injuries from intramuscular administration of vaccines more broadly. The committee that conducted the review identified sufficient evidence to draw 20 conclusions about whether these vaccines could cause ...
