  Vidcast:  https://youtu.be/C069WrAoDQ8   From TikTok viewer (user iii_1986_iii):  Is it true that once you’re immune, you’re immune because if not that would make literally every vaccine ever manufactured worthless.   We all wish that were true.  Even for# influenza, a yearly booster with different antigens is required. #Tetanus requires a 10 year booster. Even childhood vaccinations such as #MMR and #polio must be repeated if you are planning travel into an area where these diseases are present. All immunity wanes over time.   In the case of #Covid, the virus is mutating and the currently available vaccines made against the original strain are not completely protective.   Boosters are now under development by Moderna and Pfizer.   If you have a Tell Me Why, ask it via my TikTok, YouTube, or Instagram channels or email me at drhowardsmith.reports@gmail.com.
