NEW YORK, May 3, 2022 (BSS/AFP) - Pfizer reported another quarter of huge revenues growth because of the Covid-19 vaccine on Tuesday, but lowered its full-year profit forecast due in part to shifts in foreign exchange.
 
   The major American drugmaker reported revenues of $25.7 billion for the first quarter, up 77 percent from the year-ago period, with the Covid vaccine taking in $13.2 billion.
 
   Pfizer now sees full-year adjusted profits of $6.25 to $6.45 a share, down 10 cents from the previous range.
