2) This comes as 2 doses of Pfizer seeing efficacy drop in Israel. 3rd dose already planned by UK - shown to be effective.

3) Moderna will likely seek another booster dose in the near future too it sounds like. ctvnews.ca/health/coronav…
4) “Canadian stem cell biologist Derrick Rossi told CTV News Channel on Wednesday that the body’s immune system is "primed by vaccination or primary infection," however that immunity wanes over time if those systems are not challenged.”
5) "I think boosters are most likely going to be in the cards and evidence is pointing towards that so this is the evidence emerging out of Israel that a booster is almost certainly the way," Rossi said.
6) regarding the 3rd shot, I think this is a balanced take from Dr @PeterHotez - we may need 3rd dose someday, and maybe sooner for immunocompromised and weaker immune system.
