RE: COVID vaccines are not 100% effective but definitely works

The vaccine is free in Japan too. No vaccine is 100%. Some are pretty close, but there is always a risk you will get the virus anyway. But as you say, some protection is better than none.

I understand the fear of the covid vaccine. It's a new technique, there is no long term testing of this technique. Being afraid is ok. But all these conspiracy theories... it makes you magnetic, it embeds nanochips to track you... this is all nonsense. The misinformation is crazy.
