Flu vaccines are effective, but need to be changed every year due to variants. Science may lead to a universal flu vaccine...in the future.

CDC, effective?
How effective are flu vaccines?
CDC conducts studies each year to determine how well influenza (flu) vaccines protect against flu. While vaccine effectiveness (VE) can vary, recent studies show that flu vaccination reduces the risk of flu illness by between 40% and 60% among the overall population during seasons when most circulating flu viruses are well-matched to those used to make flu vaccines. In general, current flu vaccines tend to work better against influenza B and influenza A(H1N1) viruses and offer lower protection against influenza A(H3N2) viruses. See “Does flu vaccine effectiveness vary by type or subtype?” and “Why is flu vaccine typically less effective against influenza A H3N2 viruses?” for more information.

Maybe they can do the same for Coronaviruses. Anything from the common cold to Covid19. Not holding my breath as their story changes with every shift in the metaphorical wind.
