54 yrs old male. mild asthma and well controlled high bp. due to a measles outbreak in my area i received an mmr vaccine two yrs ago. i have read that the mmr vaccine can mitigate some effects of covid 19. is this true and is two years ago adequate?

Reports: There is some information regarding the MMR vaccine which is available. There is not enough information to utilize the MMR vaccine as a public health measure against COVID 19. A flu vaccine is recommended and a COVID 19 vaccine as available. Watch for signs of cough, fever and shortness of breath.

Uncertain: "There are reports that appear to suggest that several currently available vaccines already established as “safe” (including polio, Haemophilus influenzae type-B, MMR, and pneumococcal) may offer significant protection against COVID-19 via a nonspecific “innate immunity."
