Johnson & Johnson and AstraZeneca are not mRNA, so there are already non-mRNA options out there if that's a concern for you. My mom got Johnson & Johnson and felt ill for a day and I got Pfizer and didn't have any side effects at all, so it's not automatic that mRNA vaccines have worse side effects than non-mRNA ones. It mostly depends on the person. Johnson & Johnson also has a much worse reputation than the two mRNA vaccines as far as effectiveness and side effects go. However, any vaccine is way better than no vaccine, so take whatever makes you feels comfortable. Just remember that covid has bad side effects too, and we don't fully understand the long-term damage that covid causes. You can try to play it safe until the Novavax vaccine hits the market, but unless you are living in a bomb shelter, you won't be completely safe from covid until then. I don't think Novavax will be that much more effective than Johnson & Johnson that it's worth taking that risk, but if you're absolutely dead set on getting the Novavax vaccine, at least that's better than refusing to get vaccinated at all.
Who said I was dead set on novavax? Maybe I wasnt clear, sorry. Basically, I noticed some people had concerns about side effects and/or new tech in the vaccines. I was just pointing out that there were going to be more (safer) options, as it seemed some people weren't aware of this.
The only reason i mentioned novavax specifically was as an example, as it works differently than any of the ones currently available and in the last clinical trials proved safer and more effective than any currently out.
I just figured it might help some people decide to eventually get vaccinated if they knew they weren't limited to what is currently available, so was putting the info out there.
