The Oxford-Astrazeneca vaccine, marketed in India as Covishield was one of the first competitors in the race and largely considered a safe vaccine to use. However, recent reports from France, regarding certain side-effects made many consider it a tad bit unsafe for use, especially amongst the senior groups.
Nonetheless, the factsheet maintains that a person can develop some symptoms, on the milder side such as pain, warmth, itching, bruising, fatigue, chills, fever, nausea, muscle ache, lumps and malaise. Severe side-effects such as extremely high temperature (over 102 degrees Farhenheit), coughing, breathing difficulties, nervous problems, anaphylaxis are possible, though rare. It should be noted that the severe reactions, observed during the clinical studies were ruled out to be unrelated to the vaccine.
