TikTok — the short-form video app used by many young Americans — soared in popularity during the early days of the pandemic, and influencers on the platform have amassed major audiences. By chatting with a group of TikTokers — who had between 794,000 and 24.1 million followers — Fauci went directly to young Americans across the country via their phone screens to answer questions and dispel common myths about the vaccine. The President had aimed to get 70% of US adults at least one Covid-19 vaccine shot by Independence Day. If the weekly pace of vaccinations continues at the same rate as the week of May 22, only 57.5% of adults under age 30 will have received at least one dose of a Covid-19 vaccine by the end of August. The White House also built a Covid-19 student community corps to equip young people with tools to go into their communities and talk about getting vaccinated.
