Covid: less contagious those who become infected after vaccine, study

Double attack on the virus, who becomes positive in the first days post injection seems to have lower viral load

Milan, March 29 (beraking latest news Health) – Not only a shield effect against disease, but also a lower viral load in cases where the virus still manages to infect. It is the possible ‘double attack’ of the mRna vaccine at Covid-19. Some initial reports have photographed it and suggest a lower infectivity of those who become positive after being vaccinated. Specifically, a study published in ‘Nature Medicine’ takes into consideration this potential of the Pfizer vaccine. Approximately 95% effective in preventing symptomatic disease approximately 7 days after the second dose, the shield product also provides early protection starting 12 days after the first injection. But what if someone becomes infected in this time frame?

The work analyzes a set of (real-life) data on Sars-CoV-2 positive tests after vaccination. The authors found that “viral load is substantially reduced for infections occurring 12-37 days after the first dose of the vaccine,” reads an excerpt from the research. “These reduced viral loads suggest potentially lower infectivity”, a lower contagiousness that “further contributes to the vaccine‘s effect on the spread” of Covid-19.
