During takeoff I noticed an acrid/dirty sock smell; I mentioned to the captain as we began to rotate. During initial climb the fume began to get worse. Somewhere around 1000 feet I put my oxygen mask on and that is where I noticed a blue/gray fume/smoke coming from the vent above my oxygen mask case. Captain declared PAN PAN PAN and I took over communications as he began the QRH procedures. We landed back in [departure airport] and proceeded to the gate. Once passengers were off the aircraft I noticed I was not feeling well nor were the other crew members. EMT services were requested and the Captain and I were transported to the local hospital.
Just after take-off a strong; burning odor was very strong in the aft part of the aircraft. Within minutes; the CA (Captain) called and informed that we were returning to airport with a precautionary landing.On taxi-in; two F/A's (Flight Attendants) in the AFT had strong headaches immediately. FO (First Officer) and FWD FA were nauseous. FO was flushed; vomited and almost passed out. He was taken to the ER by paramedics. All 3 FA's were transported by Company to ER.
A319 pilot and flight attendant reported strong; incapacitating fumes in the cockpit and cabin immediately after takeoff; necessitating an immediate return to the departure airport.
