Taking the Covishield® vaccine does not invalidate the fast, as per the opinion of Islamic scholars. Individuals should not delay their Covid vaccinations on the account of Ramadan.
Subcutaneous, subdermal, intramuscular, interosseous, or intra-articular injections for non-nutritional purposes whilst fasting do not invalidate the fast, regardless of the injected content entering the blood circulation. These routes are not classed as entry sites that would invalidate a fast. Receiving the Covid-19 vaccine as an intramuscular injection, the only route for the vaccines currently available, therefore does not invalidate the fast.
On March 22, 2021, the Ulema Council confirmed ‘faith does not forbid Russian Muslims from getting vaccinated with Sputnik V®, after considering two components of the Covid-19 vaccine for Sharia compliance.’
