Vaccine effective for all the virus?

In spite of settlement of SARS CoV-2 in our country, miserable news are discerned from foreign countries these days, among them bad new from Germany is louder. It's because of the spread of new virus Delta stock. As we know, vaccination on the specific stock is effective only onto the stock even if there might be verbal deception in any way. There can be no exception where basic absolute principles apply anywhere, anytime. No deception or lie are acceptable in the Scientific World, no room to cut in for Emotional upset.

Vaccinations incited by fear worldwide leave many problems, they will be revealed as time passes, no miserable result will occur, so I hope. Most of us say no complaint about the measures done by our Government if done desperately regardless of effectiveness. it is a good proof that our nation is much influenced by mass emotions than the actual phenomenon.
