Does the vaccine make me contagious?

The authorized vaccines do not contain the Covid-19 virus, and you cannot develop Covid-19 from the vaccines. Therefore, the vaccines cannot make you contagious with Covid-19 to anyone you come into contact with.

But it does take time for the vaccines to reach their full protection effects. It's possible to be separately infected with the virus just before or just after vaccination and get sick. Researchers also have not yet determined whether vaccines prevent individual spread of the virus.

That's why wearing masks, social distancing, practicing hand hygiene and avoiding large gatherings remain essential after getting vaccinated.

This variant spreads twice as fast as other variants (read more about how viruses mutate here). Unvaccinated people are especially at risk of contracting Delta. According to at least two studies, patients infected with Delta had higher rates of hospitalizations than those who were infected with other COVID-19 strains. Unvaccinated people are far more…
Will the vaccine protect me against the Delta variant?
Yes – current vaccines provide at least some protection against the Delta variant. According to multiple studies (outlined here), the protection against Delta varies among vaccines. The studies estimate that the J&J vaccine is more than 67% effective, Moderna between 72 and 95% effective, and Pfizer-BioNTech between 42 and 96% effective. In addition to protecting people from contracting new variants, the vaccine is shown to reduce severity of infections and shorten recovery time. Most…
