Once the virus enters our body, we are infected. Having antibodies helped us fight the infection.
The efficacy of the vaccine indicates how well the vaccine has taught the body to make antibodies for the virus.
Thus, those vaccinated have a better chance of fighting the infection. That is why there are higher survival rates among those infected but vaccinated.
Since even vaccinated people can be infected, and since infection has a higher spread via inhalation and exhalation, wearing a mask keeps the virus out to a high extent, and helps keep the virus in as well (preventing the virus from spreading around via the infected person's exhalation).
- NamTaf 5y agoI'm saying this potentially without base, but I interpret them as making the distinction of 'infected with Covid-19' vs 'having Sars-Cov-2 in your body'. They're not exactly equal, and that distinction potentially drives how asymptomatic spread happens.
- orra 5y agoI see where you're coming from, but I don't think this is quite the right distinction. Asymptomatic infection, and presymptomatic infection, are both forms of infection. However, yes, they differ from symptomatic infection in terms of severity, no doubt due to lesser viral load. The distinction I would personally make is exposed vs infected. Being exposed to a virus doesn't mean you'll get infected, where infection is quantifiable tested with a PCR test.
