I hear you on flu shot and I see covid vaccine as a flu shot, I didn't take the h1n1 when it came around either. The suspicious thing is that over here they are reporting on the news that there are no cases of the common cold in hospitals...how curious. Are they just calling them all a case of the ronas now to create a public over-reaction? Much like the flu shot, I think it will be dodgy at best. Like you said tho, some vaccines are essential for sure and I have all those. If traveling to Canada, you will probably need it to get in I bet, I don't know how Mexico is tho.
