a new virus needs a new vaccine.
Influenza claimed millions before a vaccine was created..still kills as it mutates all the time so requires a newer vaccine.
It's not like we have a choice to do it any other way.
## my ex as a child was one of many children with Rheumatic Fever whose parents consented to a last ditch attempt at a cure by using then experimental Penicillin..it worked.
### Had a shingles vaccine today after a government media scare campaign reminded me of having a bout of it 40 years..horrendous virus that attacks the nerve endings so a flash of excruciating pain come from no-where.
