Hm. My work requires COVID testing every other week. If you've actually had COVID, you get a 90 day exemption because "that's how long immunity lasts"

- hprotagonist 6y agopost-infection-and-recovery and post-vaccination are not the same.
- room500 6y agoThe CDC recommends this 90 day window because a "positive" test result is more likely to be due to your previous illness than a new infection. Therefore, testing is useless because it gives you no useful information [1] > for adults recovered from SARS-CoV-2 infection, a positive SARS-CoV-2 RT-PCR result without new symptoms during the 90 days after illness onset more likely represents persistent shedding of viral RNA than reinfection It does NOT mean that you are suddenly susceptible after 90 days - just that after 90 days, you are less likely to be actively shedding the previous infection so the tests are useful again [1] https://www.cdc.gov/coronavirus/2019-ncov/hcp/duration-isolation.html https://www.cdc.gov/coronavirus/2019-ncov/hcp/duration-isola...
- throwawayboise 6y agoThanks for clarifying that... definitely not the message that we are getting at work, which is strictly making immunity claims. This leads many people to think either "why get vaccinated if it only lasts 90 days" or worry "does this mean I will need a booster shot every 90 days"
- bluGill 6y agoVaccines generally work enough differently from the disease that even if immunity from an infection would fade after 90 days, the vaccine can still work for years.
