You have to think of mRNA vaccines like software, unless its genetically coded in, the vaccine will only tell your body to target that particular gene code of the virus. I will not be surprise the later trial test for boosters will claim effectiveness towards Delta, or any other variants. Observe what Pfizer and Moderna are working towards convincing FDA and Congress: booster and then annual shot. Its much like your software patch and annual subscription, thats like kar-ching kar-ching $$$$$$$$$$$$. Why SG experts follow US? I can only think of 1 likeliest reason: they are invested in these companies and they will stand to gain.
