Software engineer makes good bot

Twitter account posts when vax slots open

- By Rick Sobey

As many Massachuse­tts residents struggle with finding available coronaviru­s vaccine appointmen­ts, a new social media account is helping those eligible for the vax learn when new precious slots go live.

A software engineer at a Boston biotech company has set up a Twitter account that helps Bay Staters find open vax appointmen­ts. The bot account posts about open vaccine appointmen­ts as they become available.

The @vaccinetim­e account tweets out the specific vax site and the number of new available slots when they are uploaded to the vax website. The account includes the link to sign up for an appointmen­t.

For instance, when thousands of new appointmen­ts became available at Gillette Stadium last week, the Twitter account posted, “2459 appointmen­ts available at Gillette Stadium on 02/22/2021. Check eligibilit­y and sign up at (the link).”

Dan Cahoon, who set up the bot and Twitter account, told the Herald on Tuesday that the public response has been overwhelmi­ng since his account went live.

“What’s definitely been particular­ly amazing for me is to see when it posts and then people respond saying they were able to get a vaccine because the bot posted,” said Cahoon, 31. “That in particular has been awesome to see.”

Cahoon, a senior software engineer at Ginkgo Bioworks in Boston, said he came up with the idea when co-workers were struggling with the state website to sign up for appointmen­ts.

His colleagues were spending hours refreshing the state’s website pages and also trying pharmacy websites, but they were not able to secure a slot.

“Not everyone has the ability to sit there on hours on end, refreshing the page,” said Cahoon, a Somerville resident. “So I’m hoping that it helps, especially those people, to have this other avenue to try to get their vaccinatio­ns.”

The Twitter account already has more than 10,000 followers as of Tuesday afternoon.

For those hoping to score an appointmen­t by following this account, one key tip is to enable Twitter notificati­ons so users are immediatel­y alerted about the new vax slots.

New appointmen­ts go fast. Last week, when more priority groups became eligible for the vaccine, new slots were quickly filled within minutes. The site crashed as 1 million more people became eligible for the vax.
