I have been able to get all my shots done a couple months ago and safely withstand its after effects which I am so thankful for. Albeit carried a sore arm, it was negligible overall. This isn't the same for the general population, and some still contract COVID-19 and its multitude of variants. Health experts say, we need to keep ourselves safe because the last thing we need to be in now... is end up in the hospital.
If you get struck by flu like symptoms, first course of action is not to panic. Take cues whether you have a headache, fever or unfamiliar body pain and get tested for COVID-19 immediately. Get an over the counter medicine like Naproxen Sodium (Sarimax) which is a non steroidal anti inflammatory drug that offers relief from these symptoms.
If you have headaches, fever, body pains and arthritis, this would provide relief. This is also safe to take twice a day as it can provide 12 hour relief per pill. Get them in Shopee or Lazada, leading drugstores and pharmacies for only Php 10 (suggested retail price). This is available over the counter but if symptoms persist, please see your doctor.
