Travel agencies in Thailand are selling coronavirus “vaccine tours” to the United States, as some wealthy Thais grow impatient awaiting mass inoculations that are still a month away amid the country's biggest outbreak so far.

Bangkok tour operator, Unithai Trip, has packages from 75,000 baht to 200,000 baht ($2,400 to $6,400) for trips to San Francisco, Los Angeles and New York, with prices dependent on the time gap between doses.

“Johnson & Johnson is one jab, but 90 per cent of inquires want Pfizer,” which needs about 20 days between the first and second doses, the agency's owner, Rachphol Yamsaeng, told Reuters.

My Journey Travel is offering a 10-day trip to San Francisco for a Johnson & Johnson shot and said it has received hundreds of calls in three days.
