very true. but fewer people who are vaccinated show symptoms (because their viral load is lower), they transmit the virus to others less effectively (for the same reason), and fewer of them are hospitalized (than non-vaccinated people). vaccines rarely grant 100% immunity, so if you need a guarantee, i have to disappoint you. but if you can see that vaccination (and masking) reduce the transmission and effects of the virus on the population as a whole, then i will have to respect your ability to learn and to value the health and lives of others.
