    The letter warns that while COVID-19 vaccines are important, they are not enough on their own to control transmission. Vaccinated individuals may still be susceptible in the first few weeks after vaccination. Strict public health measures like social distancing and masks are still needed due to limited vaccine supply and uncertainties around vaccine efficacy, especially for asymptomatic cases. More data is required on long-term vaccine effects and prevention of asymptomatic infection or transmission.
