The emergence of new coronavirus variants has raised questions about the efficacy of vaccines being administered against the deadly virus. There have been cases where even fully vaccinated people have tested positive for delta and lambda variants of COVID.
The truth is that vaccines never provide complete protection against viruses. They produce antibodies that help the body fight off the virus after it comes into contact with it. Some vaccines are effective even on the variant, while others do not provide as much protection. It is very difficult to say who has more antibodies after being vaccinated or who is more at risk of getting infected. But a recent study on the subject showed that the immune response to the virus depends on several factors, and one is your age.
