Hey Doctors, Hope you and your family is safe in this difficult situation. thanks for taking out time and answering my question. My parents are vaccinated dose 1 of Covishield a week before and next vaccination dose 2 is due after 6-8 weeks. Since last year we are using Arsenic Album 30 .. 4 pills empty stomach for 3 days and same repeat after 20-25 days. Now things are getting wrost and have seen many cases even after dose 1 or dose 2 people are getting infected with covid. In this case can my parents take this tablet's Arsenic Album 30 as advised by Ministry of Ayush. Will there be any contradiction with Covishield dose. Please advise. Whats your suggestion on usage on Arsenic Album 30 in this time for people who has not vaccinated yet , how effective it is? Thanks again for your time and valuable answers.
