I am going to share a concern I have for the vaccines being pushed out that use a viral vector system like in astrazenca, Jansen, sinovac and sputnek. Theses systems will have a difficult time adjusting to viral mutations in covid 19 that may require a booster shot in the future.
The flaw in these systems is that they use a harmless virus to deliver the information to make the covid 19 spike protein to make antibodies against. What will happen is that our bodies will also make antibodies to these harmless viruses so you basically are immunizing people to the deliver system aka the virus vector. If you do that the efficacy goes down so you need to choose a different virus vector or increase the dosages.
If the majority of the world gets these vaccines then we run the risk of prolonging the pandemic since the vaccine delivery system will become less effective the more times you use it in a person.
