But yeah, if you believe that it’s too early and not enough research on the effectiveness of booster shots vs. new variants then you should fall back to recommendations that have been tested for longer.
* Wear masks in areas with poor air circulation or air recirculation.
* Keep a 10ft distance from others.
* Avoid being around other people when not necessary.
* If you show symptoms or come in contact with someone who tests positive quarantine for two weeks.
* Get vaccinated and/or boosted if you haven’t already.
The CDC has been making fairly optimistic recs for the vaccinated but you can always be more cautious to your comfort level.
