Notwithstanding any general or special law to the contrary, the department of public health shall immediately establish a centralized, one-stop portal on the mass.gov website to be used to determine eligibility and allow one-stop online sign-up for COVID-19 vaccinations. Said portal shall be made available to all residents of Massachusetts and must be accessible via internet and mobile device. Said portal shall also be translated and accessible in multiple languages. The department of public health shall also establish a centralized phone number for residents of Massachusetts to determine eligibility, allow sign-up for COVID-19 vaccinations, and ask questions regarding vaccination eligibility and the vaccination sign-up process. Said phone number shall be staffed 24-hours a day, seven days per week and shall include sufficient staffing to prevent significant wait times for callers. Vaccine eligibility determination and sign-up for COVID-19 vaccinations via said phone number shall also be accessible in multiple languages. The department of public health shall, by any means practicable, share information about said portal and phone number with the general public, including, but not limited to, via the “AlertsMA” text-based notification system.
