I heard the new Novavax vaccine coming out next month is protein based?
Yes, and it will be interesting to see how it compares to mRNA vaccines. And since many unvaccinated have considered mRNA vaccines too experimental, it might offer an alternative to those.
I have just come home after flying Oslo->Prague->Amsterdam->Oslo. To sum up: unless you really need to travel abroad, don't bother, too much hassle and too unpredictable. I (recently boosted) was travelling with my daughter (unvaccined, recovered), and we needed proof of a negative PCR to travel into Czechia, and a new test after 5 days which didn't apply since we left sooner, and we needed to take an antigen test within 24h after returning to Norway (but risking to queue up at the airport for that test before allowed to leave). And we were also required to fill out passenger locator forms online before travel. Sounds fairly easy. But the PCR test has to be no older than 72 hours, and with the ongoing wave that's about how much time it takes before tests get analysed. So in the evening before we were to fly out the next morning the results were still missing, and I had to shell out for express PCR tests at nearly $250 each to get proof right away. Since I live in Oslo, it was at least practically possible to get this test (if there are vacant slots). I was told it would take 30 minutes, but hours went by, no results, so I had to go back to the test station to check before it closed for the night (they had no phone number on their website). A problem with their machine. I got my proof in the end. Maybe I didn't need it. Boosted people were exempted from testing, but whether that was valid from the first day after the shot, a week, or two weeks was impossible to find out, and mine was only a few days old. The information was ambiguous and unclear, so I couldn't risk it. These results were actually checked by the airline before boarding and those who were still waiting for the results were denied boarding. Nobody cared to check in the immigration, though. The results from the first, wasted PCR test came during the flight for my daughter and in the evening for myself, way too late. New problems when checking in for the return. They wanted to see a new recent proof of a negative test, but that was wrong. No such thing required for going to Norway. Maybe it's a requirement for the Netherlands, but we were only going there in transit. We were allowed to check in and fly eventually, but it seems to depend on how well informed the people in the counter are. And we braced for a long wait in a packed area to be tested upon arrival. Several flights were arriving at the same time, probably a thousand people in half an hour and the area reserved for people waiting to be tested appeared to be something like 50 m², perhaps capable of receiving a 1/4 full flight. Sensibly, everybody were therefore just waved past instructed to do the test at home, and buy tests at a pharmacy if necessary (which are mostly sold out, anyway). So in theory travel is possible if you do your homework, but the trouble is that whether that is good enough depends on things out of your control, like getting results in time, finding vacant slots for testing at the right time, whether people in the counter are correctly informed, and how to interpret the rules (like, the requirements and exceptions for entering Czechia differed slightly depending on whether you read the English or Czech text). I also decided to shell out for parking at the airport as extra insurance, because if I either of us had been tested at the airport after returning and got a positive result, we would have been locked up in a hotel if we had to depend on public transport to get home.
One can wonder, why bother. Yesterday, the number of new cases registered in Oslo equals more than 0.5% of the entire population. In a single day. And it's still estimated that the true number of new cases is about twice the confirmed cases.
