Claim: Only five countries in the world have made COVID-19 vaccine. India's vaccine is the most effective one.
Fact-check: Not just five, many countries are developing & manufacturing various COVID-19 vaccines - FACTLY
Verdict: while it is true that indian is one of the countries which made the covid-19 vaccine, many countries  are part of the development and manufacturing of the various covid-19 vaccines. as of today, there is no scientific evidence to claim that 'covaxin', the vaccine developed by india-based bharat biotech, is the most effective one. bharat biotech chairman dr krishna ella has said that the company expects to release the efficacy data of covaxin's ongoing phase 3 trials by march 2021. hence the claim made in the post is false.
