Can I still infect others with COVID-19 if I am vaccinated? Do I still need to wear a mask after vaccination?

The results of the studies show that the COVID-19 vaccines protect between approximately 90% and 95% (Pfizer and Moderna) against COVID-19 infection. This means that about 5% to 10% of the people who are vaccinated can still become infected with the COVID-19 virus. The AstraZeneca COVID-19 vaccine has an efficacy of 76% and the Johnson & Johnson 66.3%. Vaccinated people who do become infected with COVID-19 are less likely to experience a severe form of the disease or be hospitalised. However, the protection provided by the COVID-19 vaccines gradually decreases after a few months whereby the risk of infection for vaccinated persons increases. Therefore, getting a booster dose is strongly recommended.

New research shows that vaccinated individuals who become infected with the delta variant of COVID-19 virus can still transmit the virus. However, COVID-19 vaccination greatly shortens the number of days a person is infectious. Therefore, everyone, including those who have been vaccinated, should for the time being wear the mouth mask as prescribed by the current precautionary measures. This will not only protect you, but also your loved ones.
