Signs of the atypical clots come with serious complications every week or two after the J&J vaccination — now not immediately — in addition to stomach ache and nausea.
The New Brunswick, New Jersey-based corporate introduced closing month that it didn’t be expecting a take advantage of the vaccine this yr and used to be postponing gross sales projections.
The rollout of the corporate’s vaccine used to be harm by way of a chain of troubles, together with production issues at a Baltimore manufacturing facility that pressured J&J to import thousands and thousands of doses from in a foreign country.
