Hello I have taken sinopharm in January 2nd dose...

can you take a different vaccine in different occasion ?
currently its not porhibited to take a different vaccine in different occasions , but you should know the following :
1. one type of vaccine is enough 
2. taking 2 different vaccines isnt fully understood, therefur its not fully supported , and no immunity boosting confirmed yet due to lack of research 
3. its advised against mixing 2 vaccines in the same time 
What are the side effects of the covid vaccine:
1. Swelling and pain at the injection site
2. General weakness
3. Headache
4. Muscle and joint pain
5.  Swollen lymph nodes near the injection site
7. Vomiting and nausea
8. fever
Symptoms may appear more frequently on the second dose
our advice :
covid vaccine prevent serious complications of Covid, but it does not prevent you from getting infected 100%, and it does not prevent its transmission to others from you, and therefore you must stick to prevention methods such as masks and avoiding crowds  even after taking the vaccine
