I'd venture to guess all of us at one point or another had vaccines throughout our lives. Smallpox has killed over 300 million people since 1900. Smallpox was eradicated in the United States by 1949, and the world by 1977 and has saved millions of lives. I'm certainly not comparing the lethality between Covid-19 and Smallpox (33% lethality rate); just showing the power that mass vaccination can have on peoples lives. Vaccines can prevent all kinds of nasty virus's such as chickenpox, diphtheria, hepatits A & b, HPV, measles, meningococcal, mumps, polio, rubella, tetanus and whooping cough.
If our vaccination rate continues to hover at 50% we will be dealing with this virus for the foreseeable future.
