A year to the day of the first reported case of COVID-19 in the state, there are now three brands of vaccine in the fight against the most severe symptoms of the virus that has killed more than 21,000 New Jerseyans. Stories of second-shot sensitivities or religious concerns have prompted questions about whether it's possible to hold out for any one of the brands. As of Wednesday in the state, 2.19 million vaccines had been distributed, of which 53% have been Moderna and 47% Pfizer. So far, the Janssen vaccine from Johnson & Johnson had not yet been administered in the state. The shots are being administered by 300 vaccine sites, spanning a range of seven categories from county/municipal, mega-site, hospital, pharmacy, urgent care or medical practice, federally qualified health center or “other.”
