I was not asked by ANA if I am vaccinated or have tested negative on the Covid-19 Test before the flight while I was processed at the Departure Counter. This scenario is totally different from the time I travelled to the US in July 2021. I had to present my vaccination card, should be negative on the Covid-19 Test at least 72 hours before departure, bought a Covid-19 Insurance Policy to cover my medication expenses while abroad, and to register Online with the Immigration Office of California/USA about my trip. All of these were all gone and I guess, everything is coming back to normal just like those days before the Pandemic.
On my trip last July 2021, the first thing that I did was to have my Covid-19 vaccine a day after my arrival in Los Angeles, California. Even if I was vaccinated with Sinovac months earlier in the Philippines, my daughter advised me to have my Covid-19 shots in the US. So, I had my complete dose of the Pfizer vaccine at the Kaiser Permanente Medical Center in Los Angeles. My Vaccine Card was updated and the staff removed my Sinovac Vaccine as my first Covid-19 vaccine. Pfizer is considered as my first Covid-19 vaccine after all.
I had my booster shots with Pfizer in the Philippines last May 2022 but my 2nd booster shot did not materialize until the time I scheduled my latest trip to the US. I have it planned last November or December but I simply forgot all about it.
Now that I am here again in the US, my daughter brought me to the same Medical Center for my Bivalent Booster Covid-19 Vaccine.

I gave my Covid-19 Vaccine Card to the Medical Staff and she updated my record/file for a few minutes. She asked me to choose the Vaccine Brands available and I asked her the Moderna Bivalent Booster Vaccine which happens to be the latest Covid-19 Vaccine to be produced so far.
I can say the injection is more painful on the Moderna as compared to Pfizer. It has been a week after the vaccine but I can still feel a bit of pain from my left shoulder. Actually, the plaster or medical tape that covers the injection part is still on my shoulder. However, I did not feel any after effects of anything on my body from the Moderna vaccine.
The medical staff who attended me was kind enough to update and issue me an updated vaccine card with all the vaccines I got starting with the Pfizer I got last July 2021 up to the present. All in all, it took me less than 20 minutes stay in the said Vaccination Room as I was the only one being attended to during that time.

My first day in Los Angeles was very fruitful and rewarding.
