Study examined 1,497 full-vaccinated healthcare workers for breakthrough infections
As vaccination efforts against the coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continue globally, scientists and public health officials are dealing with the threat of breakthrough infections. Scientists call such cases “breakthrough” infections because the virus has broken through the protective barrier provided by the vaccine.
A new study published in The New England Journal of Medicine found that in a very small number of cases, people with breakthrough infections might suffer long-lasting COVID-19 symptoms .
Researchers at the Sheba Medical Center in Ramat Gan in Israel and the Harvard T.H. Chan School of Public Health in Boston revealed that although the BNT162b2 Pfizer-BioNTech COVID-19 vaccine is highly effective (94% efficacy), rare breakthrough infections carry an infectious potential and pose a unique challenge. Since these infections are mostly asymptomatic, they may increase the risk of viral spread to vulnerable populations.

To curb the spread of the virus, vaccination efforts have commenced in most countries. Currently, nearly 4.11 billion vaccine doses have been administered across the globe.
Since its rollout in late 2020 in Israel, the BNT162b2 […]
