In 1993, he was elected as a member of the Delhi Assembly representing Krishna Nagar. He was appointed as the State Minister of Health and Minister of Law for Delhi. He later became the state Minister of Education in 1996. Vardhan has been re-elected from the same constituency in the 1998, 2003, 2008 and 2013 elections.
Minister of Health and Family Affairs of Delhi
Harsh Vardhan as the State Minister of Health in 1994 oversaw the successful implementation of the pilot project of the Pulse Polio Programme which involved the mass immunisation of 1 million children up to the age of 3 in Delhi. In 1995, this programme was launched nationwide leading to 88 million children being immunised. On 28 March 2014, India was declared polio-free by the WHO, as there had been no reported cases for three years. In 1997, the Delhi Prohibition of Smoking and Non-Smokers Health Protection Act was passed in the Delhi assembly which was one of the first anti-tobacco laws implemented by any state government. The act applied across the NCT of Delhi. It prohibited smoking in places of public work or use for example hospitals, restaurants, and educational institutions and in public service vehicles. It also prohibited the sale of smoking substances such as tobacco and beedis to anyone below the age of eighteen. Smoking products could not also be sold or stored within 100 metres of any educational institution. Under the provisions of the act, fines would be applied to anyone who contravened the law and they could potentially be ejected from places of public use by the police.
2013 Delhi Assembly elections
On 23 October 2013, Vardhan was named the Chief Minister candidate for Delhi Assembly elections by the BJP. After the 2013 elections, BJP emerged as the single largest party winning 31 out of the 70 seats in the Fifth Legislative Assembly of Delhi. However, they fell short of an absolute majority so were unable to form the government.
Harsh Vardhan contested the Chandni Chowk seat in Delhi where he defeated Congress candidate Jai Parkash Aggarwal by a margin of 2,28,145 votes. While Vardhan received 52.94% votes, runner-up Aggarwal polled 29.67% votes. On 30 May 2019, Harsh Vardhan was sworn in as a cabinet minister in Prime Minister Narendra Modi's second term government. He is put in charge of the Minister of Health and Family Welfare, Minister of Science and Technology and Minister of Earth Sciences.
Controversial remarks
At the 105th Indian Science Congress in March 2018, after the death of legendary British scientist Stephen Hawking, Vardhan wrongly claimed that Hawking had said that the Vedas postulated a theory superior to Albert Einstein's theory of relativity, despite the fact that there is no record of Hawking having made the statement. In 2019, after the Health Effects Institute released a scientific report estimating 1.2 million annual deaths in India due to air pollution, Vardhan denied the results, arguing that this report was intended to create panic
