Refuah Shleima. Common sense advice – lead healthy lifestyle after that and do an overall medical checkup.
I am not sure why we are still debating pro- and against vaccines. Historical hesitancy of vaccines and greater caution in testing is due to unbalanced risks – vaccine given to whole population v. a small chance of getting sick. For example, there were 15K polio cases a YEAR in US in 1950s for 150M population. Currently, we have 80K hospital admissions per WEEK for just 2x higher population.
Thus, given a high chance of exposure to the virus for anyone who is mixing up with the public, the chance of having a virus is at best 5x lower than 100% exposure to the vaccine. Then, as already mentioned, you ismply compare risk from wild or created virus v. risk from a vaccine that was made to help, and it is obvious that vaccine risk is less. It is like comparing risk of infection v. antibiotics., or bullet and surgery.
