The 20-time Grand Slam winner has remained unvaccinated against coronavirus and has maintained that he is willing to miss out on future tennis trophies than be forced to take the jab.

Posting a video of himself playing tennis, Poonawalla, whose Pune-based firm manufactures anti-COVID-19 vaccine Covishield, tweeted, "I respect your personal views on not getting vaccinated @DjokerNole and love watching you play, but I hope you change your mind. In the meantime, the rest of us now might stand a chance at a Grand Slam."

Last month, Djokovic was prevented from participating in the Australian Open tournament due to his unvaccinated status. The 34-year-old tennis superstar was detained and eventually deported from Australia for failing to meet that country's strict vaccination requirements.

A few days ago, Djokovic was quoted as saying that he is still not vaccinated and prepared to sacrifice titles to stay that way. However, the No 1-ranked tennis player has maintained that he is not opposed to vaccinations.
