According to reports, the amount was slightly lesser than President Barack Obama’s initial request of $1.9 billion three months ago, but more than what is being proposed by House Republicans.
The Senate passed the motion with 68 votes for and 29 against.
If approved further, the Zika virus bill will be added to an unrelated spending bill.
Reports added that the House is to debate its $622 million anti-Zika measure on May 18, with the White House’s threat to veto the bill looming large because the amount seemed “woefully inadequate given the significant risk that is posed by Zika.”
The proposal reportedly warranted the pairing of the amount with balancing spending cuts to unspent Ebola funding and extra money from the Department of Health and Human Services.
The Democrats also nipped in the bud a Republican-backed proposal to breach Obama’s health care law fund.
The battle against Zika virus is known to cause severe birth defects including microcephaly.
